Fletching clearence tool

ABSTRACT

This invention simply moves your arrow forward on your rest to check the clearance between your fletching and the bow riser. This device is comprised of two tubes one being able to slide inside the other. One end has an arrow nock or clip attached, so it could be attached to the bowstring. The other side is fitted with an internally tapered cup to allow your arrow nock to slide into it. This cup may also have a pin or divider inside to allow your arrow to clip onto it. This invention can slide open to accommodate most brace heights. This invention aids in the bow and arrow tuning process. The sliding tubes may have a rail and raised guide channel attached to prevent turning. The smaller diameter tube may have a raised rail its entire length. The larger diameter tube may have a raised guide channel its entire length to allow the small tube to slide open without turning.

BACKGROUND OF INVENTION

[0001] 1) Field of Invention

[0002] This invention relates to a device that will aide in the tuning of the bow and arrow by allowing a visual check of your arrow fletching clearance against the riser

[0003] 2) Description of Prior Art

[0004] I claim unlike other art designs, my invention allows for a visual check of your arrow fletching clearance against the bow riser.

SUMMARY OF INVENTION

[0005] A bow-tuning device comprised of two tubes one being able to slide inside the other. One end has an arrow nock attached so it can be attached to the bowstring. The other side is fitted with an internally tapered cup to accommodate your arrow nock. This cup may also have a pin or divider inside to allow your arrow to clip onto it. The sliding tubes may have a rail and raised guide channel attached to prevent turning. The smaller diameter tube may have a raised rail its entire length. The larger diameter tube may have a raised guide channel its entire length to allow the small tube to slide open without turning.

[0045] While certain specific details have been disclosed hear in, it is not intended to limit

[0046] This invention to the precise details disclosed since various changes and modifications will suggest themselves to anyone skilled in the art that may read this specification. 

1. A bow-tuning device comprised of two tubes one being able to slide inside the other. One end has an arrow nock attached so it can be attached to the bowstring. The other side is fitted with an internally tapered cup to accommodate your arrow nock. This cup may also have a pin or divider inside to allow your arrow to clip onto it.
 2. I claim this invention will aid in the bow and arrow tuning process by allowing a quick check with your arrow to insure that there is no fletching contact with the bow riser.
 3. I claim the sliding tubes may have a rail and raised guide channel attached to prevent turning. The smaller diameter tube may have a raised rail its entire length. The larger diameter tube may have a raised guide channel its entire length to allow the small tube to slide open without turning.
